Abstract
LA PRESENTE INVENCION SE REFIERE A UNA DISPOSICION (20) PARA TRANSMISION DUPLEX EN UNA RADIO O SIMILAR CON TRANSMISOR (1) Y RECEPTOR (2), COMPRENDIENDO LA DISPOSICION UN FILTRO DE TRANSMISOR (3), UN FILTRO DE RECEPTOR (4) Y PREFERENTEMENTE UN DISPOSITIVO TRANSMISOR/RECEPTOR (5), EN EL QUE EL FILTRO RECEPTOR (4) COMPRENDE UN FILTRO LLAMADO FILTRO SAW (FILTRO DE ONDA ACUSTICA DE SUPERFICIE) Y EL FILTRO TRANSMISOR (3) Y EL FILTRO SAW (4) ESTAN CONECTADO POR UN CIRCULADOR (6). LA DISPOSICION COMPRENDE UN DISPOSITIVO DE DETECCION DE POTENCIA (7) PARA DETECTAR LA POTENCIA EN/HACIA LOS FILTRO RECEPTORES (FILTROS SAW) Y LA DISPOSICION DE DETECCION DE POTENCIA (7) PREVE UNA SEÑAL DE REALIMENTACION HACIA UNA DISPOSICION DE CONTROL PARA CONTROLAR LA POTENCIA FUERA DE UN AMPLIFICADOR DE POTENCIA DISPUESTO ENFRENTE DEL FILTRO TRANSMISOR (3).THE PRESENT INVENTION REFERS TO A PROVISION (20) FOR DUPLEX TRANSMISSION ON A RADIO OR SIMILAR WITH TRANSMITTER (1) AND RECEIVER (2), THE DISPOSITION INCLUDING A TRANSMITTER FILTER (3), A RECEIVER FILTER (4) AND PREFERABLY A TRANSMITTER / RECEIVER DEVICE (5), IN WHICH THE RECEIVER FILTER (4) INCLUDES A FILTER CALLED SAW FILTER (SURFACE SOUND WAVE FILTER) AND THE TRANSMITTER FILTER (3) AND THE SAW FILTER (4) ARE CONNECTED BY A CIRCULATOR (6). THE PROVISION INCLUDES A POWER DETECTION DEVICE (7) TO DETECT THE POWER IN / TOWARD THE RECEIVING FILTERS (SAW FILTERS) AND THE POWER DETECTION PROVISION (7) PROVIDES A FEEDBACK SIGNAL TOWARDS A CONTROL DEVICE FOR CONTROLLING OUTSIDE A POWER AMPLIFIER ARRANGED IN FRONT OF THE TRANSMITTER FILTER (3).
